The dual coding theory proposed by Paivio attempts to give equal weight to verbal and non-verbal processing. Paivio (1986) states: Human cognition is unique in that it has become specialized for dealing simultaneously with language and with nonverbal objects and events.
Therefore, high temperatures are required to break these strong bonds to turn it into a liquid state â¦ . Thus the melting point of graphite is high, same goes for diamonds. Even though it is a covalently bonded compound, these 2 examples are the only ones that have high melting points. The melting point of graphite is 3500 c and 6332 f, specific gravity is 2.25, pounds per cubic inch is .812, 21 people found this useful.
The melting point is the temperature at which a solid will turn into a liquid, and the boiling point is the temperature at which a liquid will turn into a gas.or White phosphorus, the Boiling point is 280.5 Â°C and the Melting point is 44.2 Â°C.    Check out the right hand table on this page for more information on the other â¦ types:   http://en.wikipedia.org/wiki/Phosphorus. 4 people found this useful.
